Celebrate Colorado Day

Some museums offer free admissions to the public and a number of businesses in Colorado offer special deals or discounts for products and services to celebrate the day.

Public life

Colorado Day is a state observance on August 1. It is not a public holiday in the U.S., so most businesses, public offices, schools and colleges are open except for if the date falls on a non-working day.

About Colorado Day

On August 1, 1876, president Ulysses S. Grant signed a proclamation admitting Colorado as a state. Colorado Day was celebrated as a state holiday on August 1 for many years, and then was moved to the first Monday in August, most likely after the time the U.S. Congress passed the Uniform Holidays Bill in 1968. The day no longer became a public holiday, but rather an observance, when the state started observing Martin Luther King Jr. Day as a public holiday in 1985.
